i was told the flat rate envelopes could not hold ANY fabric- that the envelopes were for documents' sheets of paper only---my p.o. made me switch the contents of my envelope to a tyvek bag type of packaging....which of course is not (flat-rate)
postage increases along with gas price increases are sure changing the way i do things...and the things i get to do- continuous running swaps- programs i've had to stop signing up for --which is a bumber- but a second job is out of the question right now...
